Notes

Notes on data extraction

  1. These attributes will be extracted from articles that pass title and abstract screening, as well as full text screening. Attributes are categorized to encompass bibliographic information, population information, intervention information, etc. Outcome attributes, such as outcome category and subcategory, outcome description, etc. will be repeated for each outcome (e.g., coral condition, waves).
